5 mistakes we make while brushing our teeth (and how to prevent them)
Share
Most of us brush twice a day and still miss the mark. Technique matters more than intensity: the wrong moves can irritate gums, leave plaque behind, and shorten the life of your enamel. Here are five common mistakes and some easy, practical fixes.
1. Brushing like you’re polishing a pan
Sometimes we’re scrubbing really hard with long back-and-forth strokes. Heavy pressure erodes enamel and pushes gums back, exposing sensitive root surfaces.
Easy fix:
Use a soft brush (manual or electric) and light pressure. Aim the bristles ~45° toward the gumline and make short, gentle strokes (or let a powered brush do the work). Think “massage,” not “scrub.” Hold the brush with just your fingertips. If you’re whitening your knuckles, you’re already pressing too hard.
2. Doing the 45-second speed run
Who often rushes and keeps brushing for less than two minutes? Plaque is stubborn, especially along the gumline and around molars.
Easy fix:
Two minutes, twice daily. Divide your mouth into 4 zones and give each 30 seconds. Many electric brushes have built-in timers; with a manual brush, set your phone or hum a song that’s about two minutes long. Switch your starting spot weekly so you don’t always run out of time on the same teeth.
3) Ignoring the spaces between teeth
Most people only brush to keep their teeth clean. Bristles don’t reach tight contact points. That’s where gum inflammation and cavities love to start.
Easy fix:
Clean between teeth at least once a day with floss or interdental brushes (choose the size that slides in without force). If you use mouthwash, do it after you’ve cleaned between teeth so it can reach those areas. Keep floss/interdental brushes where you actually use them – desk drawer, car, or coffee station – not just the bathroom cabinet.
4. Brushing at the wrong time
Brushing immediately after acidic food or drinks (citrus, soda, wine) can be dangerous. Acid softens enamel temporarily; brushing right away acts like sandpaper.
Easy fix:
Wait 30–60 minutes after acids. Rinse with water (or a fluoride rinse) right away to neutralize, then brush later. If mornings include orange juice or acidic smoothies, brush before breakfast and rinse after.
5. Using the wrong tool for too long
Hard bristles, oversized heads, and worn-out brushes – sounds familiar? Hard bristles + pressure = recession; big heads miss tight areas; frayed bristles don’t clean effectively.
Easy fix:
Choose soft bristles and a head that reaches back molars comfortably. Replace your brush or electric head every 3 months (or sooner if the bristles splay). Set a calendar reminder or change brush heads every time the season changes.
BONUS: A simple, dentist-approved routine
1. Night: Floss/interdental clean → Brush with fluoride toothpaste (2 min) → Spit, don’t rinse (leave fluoride on).
2. Morning: Brush (2 min) → Alcohol-free rinse.
3. After acids: Water rinse first; brush after 30–60 minutes.
Better brushing isn’t about doing more – it’s about doing it right. Light pressure, the right timing, and a consistent two-minute habit will do more for your teeth and gums than any heroic scrubbing ever could.
